Reaction Rates Flashcards
What is being formed during a chemical reaction
A new substance
What may a chemical reaction result in
Change of appearance
What type of reaction gives out heat energy
Exothermic
What type of reaction takes in heat energy
Endothermic
What are not chemical reactions
Dissolving, melting, boiling, freezing and condensing
What is the speed a chemical reaction go called
Rate of reaction
How can you increase the speed of a chemical reaction
Increasing the temperature, increasing the concentration, decreasing particle size,
using a catalyst
What are all substances made out of
Atoms or molecules
What happens if you increase the temperature in a chemical reaction
Makes more collisions between particles therefore a faster reaction
What is a catalyst
A substance that speeds up a chemical reaction without being used up
Where does the reaction occur with a catalyst
Active site
What is a biological catalyst
Enzymes
What is the rate of reaction equation
Rate of reaction=quantity/time
